This bestselling book is now the standard guide to building phone systems with Asterisk, the open source IP PBX that has traditional telephony providers running scared! Revised for the 1.4 release of the software, the new edition of Asterisk: The Future of Telephony reveals how you can save money on equipment and support, and finally be in control of your telephone system.

The book includes:A new chapter on managing/administering your Asterisk systemA new chapter on using Asterisk with databases Coverage of features in Asterisk 1.4A new appendix on dialplan functionsA simplified installation chapterNew simplified SIP configuration, including examples for several popular SIP clients (soft phones and IP telephones)Revised chapters and appendicies reviewed and updated for the latest in features, applications, trends and best-practicesAsterisk is revolutionizing the telecom industry, due in large part to the way it gets along with other network applications. While other PBXs are fighting their inevitable absorption into the network, Asterisk embraces it. If you need to take control of your telephony systems, move to Asterisk and see what the future of telecommunications looks like.
